Abstract: The T-post puller is a device adapted for attachment to the a post hole digger boom of a tractor. The puller has a hollow body with a skirt at its bottom, which aids in positioning the main body over the T-post. A spring-biased, pivotally mounted wedge or ratchet plate extends along the interior length of the main body for engagement with any of the post's studs. The puller is further provided with a post release mechanism in the form of a rope attached to a lever connected to the wedge plate. The body has at least one yoke extending outwardly from the top end of the body for pivotal attachment to the boom. An adapter is attachable to the yoke in order to attached the puller to other power lifting booms or machines.
